Spectrogram steganography
WebA spectrogramis a visual representation of the spectrumof frequenciesof a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfall displays. Webthe spectrogram representation we study (the STDCT) is a determinis-tic operation allowing perfect (inverse) reconstruction. Consequently, via employing spectrograms for residual audio steganography, we preserve the simplicity of not requiring an encoder for the host signal— but we expand our approach by allowing it to also encode locality.
